Exempel på hur du använder CYANO i en mening

• The name is also used for the CN radical, and hence is used for compounds such as cyanogen bromide (NCBr) (but see also Cyano radical).
• In organic chemistry, a cyanohydrin or hydroxynitrile is a functional group found in organic compounds in which a cyano and a hydroxy group are attached to the same carbon atom.
• The cyano in the term cyanobacteria refers to its colour, not to its relation to cyanides, though cyanobacteria can catabolize hydrogen cyanide during nitrogen fixation.
• In this general Michael addition scheme, either or both of R and R' on the nucleophile (the Michael donor) represent electron-withdrawing substituents such as acyl, cyano, nitro, or sulfone groups, which make the adjacent methylene hydrogen acidic enough to form a carbanion when reacted with the base, B:.
• This is followed by ring closure via nucleophilic attack on the cyano group, after which the imidate intermediate is rearomatized.
• In order to allow efficient magnetic, metal ions should be bridged by small ligands allowing for short metal-metal contacts (such as oxo, cyano, and azido bridges).
• It is possible to use benzoyl chloride but the yields and regioselectivity of the addition of the cyano group are lower.
• In contrast, cyanoborohydride is a weaker reductant owing to the electron-withdrawing cyano substituent.
• AtzA was shown to displace fluoride as well as chlorine but not azido, cyano, methoxy, which are of similar size and electronegativity, or thiomethyl or amino groups.
• Three cyano groups of the cyanate ester are trimerized to a triazine ring structure, hence the T in the name.
• Treatment of this intermediate with 3-ethyl-N-methylaniline leads to addition to the cyano group and formation of the corresponding diaryl guanidine, aptiganel, 3.
• Treatment of that intermediate with Raney nickel reduces the cyano group to the corresponding primary amine; this product then undergoes an internal ester-amine interchange to yield the cyclized lactam (5).
• Radical hydrothiolation of an unsaturated functional group indirectly generates a carbon-centered radical, which can then cyclize intramolecularly onto alkenes, oxime ethers, isocyanides, cyano groups, and aromatic rings.
• This intermediate was treated with thionyl chloride and disulfur dichloride to convert the oxime to a cyano group and chlorinate the imidazole in the position next to the phenyl ring.
